"about 7,200 miles, or 1,500 kilometers, per hour"
Sad to see that on the real NASA website. I'm guessing the 7200 miles is correct, and they typoed 11,500km. It just jumped out as so obviously wrong as I skimmed it.
A 300uS shutter speed seems pretty high for a space based ground imaging camera. Does the LRO actually need a shutter speed that high? I'm surprised it's even capable of that.

> Would it be possible to simply tilt the camera at the same apparent rate as the ground is moving?
Perhaps possible, but would it be lighter, more robust, or cheaper? My understanding is that solid state things are generally much more robust, and in these days of microchips, usually easier to implement.
Well, most consumer cameras are capable of 250μs shutter speeds, and prosumer cameras faster than that. And they're not zipping around their subject at several km/s.
